to me in Italy, No. 41,269, XXXI, dated April 4, 1896; in Germany, No.91,013, dated May 15, 1896; in Austria, No. 46/2526, dated May 21, 1896;in Hungary, No.6,2l4, dated May 28, 1896; in England, No. 20,813, datedSeptember 21, 1896; in Switzerland, No. 13,051, dated September 21,1896; in Norway, No. 5,331, dated September 25, 1896, and in Belgium,No. 123,831, dated October 13, 1896,) of which the following isaspecification, reference being had therein to the accompanying drawings.

This invention has for its object an apparatus by which sculpturedimages or works of art may be made from a model. This apparatus ischaracterized, essentially, by the various devices being concentrated atone place and being capable of being operated by one person.

The object ofthe invention is shown in the accompanying drawings, inwhich- Figure 1 is a front elevation of the apparatus. Fig. 2 is asection on theline 2 2 of Fig. 1. Fig. 3 is a front elevation of theadjustable frame and showing a modification. Fig. 4 is a side elevationof the'operating mechanism. Fig. 5 is a similar view of the cuttingmechanism. Fig. 6 is a detail of the operating mechanismj Theconstructive arrangement is as follows: Two supports or standards 2 areadj ustably arranged on two slideways 1, standing opposite one auother,and these two frames or supports are connected with one another by meansof a screwed spindle 5, mounted in a support 3 and provided with achain-wheel 4, so that by revolving said screwed spindle in onedirection or the other the two supports or frames 2 may be movedmutually to left or right. The upper end of each support carries aguide-bar 6, intended to support the main frame 7. provided withangle-bars 8, which serve as guides and partly inclose the guide-bars 6.A vertically-adjustable frame A is mounted For this purpose the latteris in the framework 7, and consists of two cross bars or beams 9 and 10,inner vertical guidebars 11, and side racks 12. A second horizontal beam13 is mounted on the bars 11 and racks 12 and may have its height variedby means of pawls 14, arranged on it so as to engage in the racks 12.The frame A is thus divided into three vertical divisions orcompartments, which serve for holding the model 15 and the works of artor images 16, which are to be made.

In order to be able to fix in the frame the model and the rough blocksfor the images which are to be made, the crossbar 13 is provided withset-screws 17, which have at their lower ends a spiked holder 18, whilethe lower cross-bar 10 is provided with supports 19. These supports 19consist of a crown-holder connected to a worm-wheel 21', revoluble onstuds 20. A worm-shaft 22 is also mounted in the frame A, so that theworm-wheels 21 may be thereby operated and the model 15 and the blocks16 thus rotated evenly on their vertical axes..

The frame A may be counterbalanced by 'counterweights connected withchains 23,

the arrangement of the aforesaid supports 19 and worm-shaft 22, and itis also necessary that the frame A should be vertically adjustable inthe framework 7 and the framework 7 horizontally on the supports 2 andthe whole in another horizontal direction on the slide way 1. In orderto effect all this, the follow in g arrangement is adopted: The lowercrossbar 10 of the frame A is provided with a slideguide 242,111 which ascrew-nut 25 may be adj usted in the direction of the arrows 26 and 27.As shown in Figs. 2 and 4, a stand 28 is arranged behind the wholeframework, which stand carries a fixed vertical screwed spindle 29. Onthis screwed spindle, the upper end of which carries the adjustablecopying-point 30, a support or frame B slides, which carries ahorizontally-arranged screwed spindle 31, which engages in the screw-nut25, Figs. 1 and 3. adjustment of the support B and therewith of theframe A with the model 15 and the images. 16, the support-frame B isprovided with a sleeve or socket 32, Fig. 6, which loosely surrounds thespindle 29 and carries a spline 34, corresponding with a groove 33 inthe screwed A bevel-wheel 35 is inserted bespindle 29. tween the sleeve32 and the upper part of the support-frame B, and the nave of saidbevelwheel is formed as a screw-nut and engages the screwed spindle 29.By turning this bevelwheel a vertical adjustment of the whole support Bis obtained. In order, however, to render possible an even rotationofthe bevelwheel, a second bevel-wheel 36, to engage the former, ismounted in the support-frame B and may be operated by means of acrankhandle 37. The screwed spindle 31 is revolubly mounted in thesupport-frame B, and the inner end of the same carries a bevelwheel 38,standing in engagement with a bevel-wheel 40, Fig. 6, which is alsomounted in the support-frame B and provided with a crank-handle 39, sothat by moving the crank 39 a rotation of the screwed spindle 31, andthereby the adjustment of the frame 7 in the supports 2 in thedirections of arrows 41 or 42, respectively, may be effected. (See Figs.2 and 4.) Thus by operating the crank 37 a vertical adjustment of theframe A, and by operating the crank 39 a horizontal adj ustment of theframe 7, is effected.

In order, however, to be able to operate the screwed spindle 5, Figs. 1and 4, for adj'usting the whole system from the standard or support 28,a chain-wheel 43 is mounted in the latter, which is connected with thechainwheel 4 by means of a chain 44. The axle of the chain-wheel 43 isprovided with pedals 45 to be operated by the person using the appa-.

ratus in the same way as bicycle-pedals. The stand 28 is also providedwith a seat 46, on which the person using the apparatus can placehimself.

The necessary borers or tools for making the image are mounted behindthe frame in the plane of the copying-point 30 and in a frame 47,composed of two movable parallelograms. (See Fig. 5.) The front of thisframe is intended to receive a revoluble sleeve or socket 49, providedwith a borer 48, while in the rear spindles 50, carrying pulleys 51, aremounted, corresponding with the sockets 49 and carrying the same withthem when rotated.

The. parallel-shaped frame has for its object to allow of the variousborers 48 being simultaneously and equally adjusted on their axes, whilepreventing any sidewise adjustment of the same, and this is effected bythe said frame being pressed together or collapsed.

In order to render possible a vertical In the form of construction shownin Fig. 5 the rear of this parallelogram is presumed to be fixed and allthe other parts to be movable; but the case may be reversed, so that thefront may be fixed and all the other parts remain movable. As, however,it may happen with certain images that they have recessed parts orhollows widening inward, for the making of which the vertical andhorizontal movement does not suffice, it is necessary that the frame Amust be capable of being oscillated on its horizontal axis. Fig. 3 showssuch an extended form of construction.

A frame 52 is arranged so as to be vertically adjustable in theframework 7 and receives the frame A, oscillating on trunnions 53. Aslide-guide 24 is mounted on the frame 52. Otherwise the frame A, isarranged exactly like that described in Figs. 1 and 1.

The mode of operation of this apparatus is as follows: The blocks 16,which are to be treated, and the model 15 are gripped in the frame A,and the borer 48 is set in rotation. The person using the apparatus thensits on the seat 46 and effects the adjustment of the frame A or thesaid frame, together with the frame 7, in such a way that thecopying-point 30 comes in contact with the model. The borers 48 work upto this depth on the blocks 16 and reproduce in this way the plasticcharacteristics of the model 15. If an adjustment or shifting of theentire device becomes necessary, the person using the apparatus operatesthe pedals 45, so that the screw-spindle 5 comes into action. If themodels have recesses widening inward, the frame shown in Fig. 6 isinserted in the framework 7, so that it is possible to allow the modeland the images to also oscillate on a horizontal axis and thereby toreach or have access to all the inner spaces of the model.
